| titleOfInvention | A method for improving the cycle performance of high-nickel cathode materials |
| abstract | The invention discloses a method for improving the cycle performance of a high-nickel positive electrode material, comprising the following steps: (1) using a saturated lithium salt solution to process the high-nickel positive electrode material, wherein the saturated lithium salt solution is added with manganese salt additives; ( 2) after the treatment is finished, carry out solid-liquid separation, drying and pulverizing, and then calcining in an oxygen atmosphere to obtain a high-cycling performance high-nickel positive electrode material; the high-nickel positive electrode material Ni 2+ /Li + mixed by the method of the present invention is processed. The displacement is significantly lower than that of deionized water only. Under the cut-off voltage of 2.75-4.3V and the 1C charge-discharge system, it shows stable cycle performance, which has a greater performance than the existing lithium-ion batteries on the market. promote. |
